The FF102\/50 is designed for use within cavities of up to 50mm and once installed, it will close the remaining free air gap in front of the 6mm cavity barrier of up to a maximum of 44mm (depending on construction type).","brand":"AIM","offers":[{"title":"Default Title","offer_id":50600171143332,"sku":"4968","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4496\/1700\/files\/AIM_FF102-50_main.jpg?v=1764647271"},{"product_id":"fischer-ffb-vs-25-251-300-ventistop-cavity-barrier-521525","title":"fischer FFB-VS 25 251-300 VentiStop Cavity Barrier \n[521525]","description":"FFB-VS 25 251-300 is a foil-faced stone wool pre-cut unit with a powerful intumescent graphite strip that is bonded to the exposed face.
